What do I do?

I just got out of a "relationship" with someone of just short of a year he cheated on me twice and set up boundaries of people I wasn't allowed to talk to especially other guys (I have more guy friends than girls) he never said we were in a relationship we were always just "talking" but it's been over a month said I said I was done now one of my guy friends (one he specifically said i wasn't allowed to talk to) asked me out on a date i politely said i wasn't ready for a relationship yet bc I'm not exactly over the last one and it wouldnt be right for me to start something. A cording to a young lady in my class he cheated on her but I knew nothing of it and he wouldnt be afraid to tell me we talk about everything. But hes a great friend hes always been there in and out through everything should I give him a chance when I'm ready or should I not risk our friendship.
